TL;DR: The 8th edition of the American Joint Committee on Cancer (AJCC) staging of epithelial cancers of the esophagus and esophagogastric junction presents separate classifications for clinical, pathologic, and postneoadjuvant stage groups, with the role of ypTNM classification in additional treatment decision-making currently limited.
Abstract: The 8th edition of the American Joint Committee on Cancer (AJCC) staging of epithelial cancers of the esophagus and esophagogastric junction (EGJ) presents separate classifications for clinical (cTNM), pathologic (pTNM), and postneoadjuvant (ypTNM) stage groups. Histopathologic cell type markedly affects survival of clinically and pathologically staged patients, requiring separate groupings for each cell type, but ypTNM groupings are identical for both cell types. Clinical categories, typically obtained by imaging with minimal histologic information, are limited by resolution of each method. Strengths and shortcomings of clinical staging methods should be recognized. Complementary cytology or histopathology findings may augment imaging and aid initial treatment decision-making. However, prognostication using clinical stage groups remains coarse and inaccurate compared with pTNM. Pathologic staging is losing its relevance for advanced-stage cancer as neoadjuvant therapy replaces esophagectomy alone. However, it remains relevant for early-stage cancers and as a staging and survival reference point. Although pathologic stage could facilitate decision-making, its use to direct postoperative adjuvant therapy awaits more effective treatment. Prognostication using pathologic stage groups is the most refined of all classifications. Postneoadjuvant staging (ypTNM) is introduced by the AJCC but not adopted by the Union for International Cancer Control (UICC). Drivers of this addition include absence of equivalent pathologic (pTNM) categories for categories peculiar to the postneoadjuvant state (ypT0N0-3M0 and ypTisN0-3M0), dissimilar stage group compositions, and markedly different survival profiles. Thus, prognostication is specific for patients undergoing neoadjuvant therapy. The role of ypTNM classification in additional treatment decision-making is currently limited. Precision cancer care advances are necessary for this information to be clinically useful.

TL;DR: The American Joint Committee on Cancer (AJCC) Cancer Staging Manual for epithelial cancers of the esophagus and esophagogastric junction are separate, temporally related cancer classifications as mentioned in this paper.
Abstract: Answer questions and earn CME/CNE New to the eighth edition of the American Joint Committee on Cancer (AJCC) Cancer Staging Manual for epithelial cancers of the esophagus and esophagogastric junction are separate, temporally related cancer classifications: 1) before treatment decision (clinical); 2) after esophagectomy alone (pathologic); and 3) after preresection therapy followed by esophagectomy (postneoadjuvant pathologic) The addition of clinical and postneoadjuvant pathologic stage groupings was driven by a lack of correspondence of survival, and thus prognosis, between both clinical and postneoadjuvant pathologic cancer categories (facts about the cancer) and pathologic categories This was revealed by a machine-learning analysis of 6-continent data from the Worldwide Esophageal Cancer Collaboration, with consensus of the AJCC Upper GI Expert Panel Survival is markedly affected by histopathologic cell type (squamous cell carcinoma and adenocarcinoma) in clinically and pathologically staged patients, requiring separate stage grouping for each cell type However, postneoadjuvant pathologic stage groups are identical For the future, more refined and granular data are needed This requires: 1) more accurate clinical staging; 2) innovative solutions to pathologic staging challenges in endoscopically resected cancers; 3) integration of genomics into staging; and 4) precision cancer care with targeted therapy It is the responsibility of the oncology team to accurately determine and record registry data, which requires eliminating both common errors and those related to incompleteness and inconsistency Despite the new complexity of eighth edition staging of cancers of the esophagus and esophagogastric junction, these key concepts and new directions will facilitate precision cancer care CA Cancer J Clin 2017;67:304-317 © 2017 American Cancer Society

TL;DR: In esophageal cancer, pN+, increasing number of positive nodes, and increasing pN classification are associated with deeper invading, longer, and poorly differentiated cancers, so few nodes need to be removed if the goal of lymphadenectomy is to accurately define pN+ status of such cancers.
Abstract: Objectives:To identify the associations of lymph node metastases (pN+), number of positive nodes, and pN subclassification with cancer, treatment, patient, geographic, and institutional variables, and to recommend extent of lymphadenectomy needed to accurately detect pN+ for esophageal cancer.Summar

TL;DR: Use of older lymph node maps and inconsistencies in interpretation and application of definitions in the IASLC lymph node map may potentially lead to misclassification of stage and suboptimal management of lung cancer in some patients.

TL;DR: With many consumers choosing or failing to switch out of plans that offer insufficient coverage, incorporating insights on consumer decision making with personalized information to estimate costs can improve the quality of health insurance choices.
Abstract: Health insurance is among the most important financial and health-related decisions that people make. Choosing a health insurance plan that offers sufficient risk protection is difficult, in part because total expected health care costs are not transparent. This study examines the effect of providing total costs estimates on health insurance decisions using a series of hypothetical choice experiments given to 7,648 individuals responding to the fall 2015 Health Reform Monitoring Survey. Participants were given two health scenarios presented in random order asking which of three insurance plans would best meet their needs. Half received total estimated costs, which increased the probability of choosing a cost-minimizing plan by 3.0 to 10.6 percentage points, depending on the scenario ( p < .01). With many consumers choosing or failing to switch out of plans that offer insufficient coverage, incorporating insights on consumer decision making with personalized information to estimate costs can improve the quality of health insurance choices.

TL;DR: It is found that beneficiaries pay more for Medicare Part D plans with gap coverage and no deductible, and higher premiums for more extensive coverage exceeded savings in deductible and copayment/coinsurance costs.
Abstract: This article examines whether California Medicare beneficiaries with HIV/AIDS choose Part D prescription drug plans that minimize their expenses. Among beneficiaries without low-income supplementation, we estimate the excess cost, and the insurance policy and beneficiary characteristics responsible, when the lowest cost plan is not chosen. We use a cost calculator developed for this study, and 2010 drug use data on 1453 California Medicare beneficiaries with HIV who were taking antiretroviral medications. Excess spending is defined as the difference between projected total spending (premium and cost sharing) for the beneficiary's current drug regimen in own plan vs spending for the lowest cost alternative plan. Regression analyses related this excess spending to individual and plan characteristics. We find that beneficiaries pay more for Medicare Part D plans with gap coverage and no deductible. Higher premiums for more extensive coverage exceeded savings in deductible and copayment/coinsurance costs. We conclude that many beneficiaries pay for plan features whose costs exceed their benefits.
